Crystallization filter

The utility model discloses a crystallization filter which comprises a filter box and a crystallization tank, vibration plates are movably installed on the two sides in the filter box, springs are fixedly installed on the opposite faces of the vibration plates at equal intervals, storage boxes are fixedly installed on the opposite faces of the springs, and filter screens are fixedly installed at the bottoms of the storage boxes. Vibration motors are fixedly mounted on the two sides of the filter box, and the output ends of the vibration motors penetrate through the two sides of the filter box to be fixedly connected with a vibration plate. In the daily use process of the crystallization filter, raw materials are poured into the crystallization tank from the feeding pipe, sodium molybdate can be obtained and enters the storage box through the discharging pipe, then the vibration motors are started, and the sodium molybdate can be obtained; the output end of the vibration motor can transmit excitation force to
